摘要

Abstract

在自然界中贵金属元素通常含量很低，在花岗岩矿石中一般只有零点几个ppm。其中Os，Ru，Rh，Ir更少，只有几个ppb

[1]

。因此对微量贵金属元素的测定，需要一种灵敏的分析方法。中子活化分析法是一种很理想的方法，但中子辐照后要进行分离以除去大量的贱金属元素，G. Koster等人

功能团的螯合树脂后，G. H. Morrison等人

[3～5]

在贵金属中子活化分析中使用此类牌号为Srafion NMRR的螯合树脂，使复杂的放化分离简化为一步分组分离，结合使用高分辨率Ge（Li）探测器测定各贵金属元素的含量，可用于环境样品中七种贵金属元素的同时测定

made by Nankai university were used. Adsorptions of Rhodinium and Iridium on resins were measured unde static conditions at different concentration of HCl at room temperature and 100℃ using

Rh and

Ir as indicators. The adsorption reached

80% for Rh

III

and

90% for Ir

at optimal conditions. It was found that these chelating resins have higher selectivity for noble metals than most of other metal ions. (Al

etc.)
